We look at the division of 865653 by 49 
The aim is to understand the frequency of 49 in 865653.

On to step 1:
49 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 49

Step 2:
When dividing 86 by 49, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 37 after subtracting 49 from 86.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 49

Advancing to step 3:
49 goes into 375 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 32 after subtracting 343 from 375.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 49

Moving on to step 4:
When dividing 326 by 49, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
Subtracting 294 from 326 leaves us with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 49

Step 5:
When dividing 325 by 49, we get 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 1766.0
If we take 294 away from 325, we end up with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 49

Going ahead to step 6:
49 can be fit into 313 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 17666.0
If we subtract 294 from 313, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
49 goes into 190 3 times with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 17666.3
If we take 147 away from 190, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
If we divide 430 by 49, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 17666.38
Subtracting 392 from 430 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
When dividing 380 by 49, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 17666.387
The remainder is 37 after subtracting 343 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
370 divided by 49 is 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 17666.3877
Subtract 343 from 370 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 17666.3877 with a remainder of 0.00027.
